Product Dissection

Before doing anything else, we dissected our drill to take a look at each part up close and understand how the drill works from a technical standpoint.


Part Description Qty Function
001 Battery 1 Provide electricity
002 Support Handle 1 Provide support for non-dominant hand
003 Supp. Handle Screw 1 Secure Support Handle
004 Nut 1 Secure Support Handle Screw
005 Screw 4 Secure Case
006 Screw 1 Secure Case
007 Screw 7 Secure Case
008 Casing Part 1 Hold in parts
009 Casing Part 1 Hold in parts
010 Strap 1 useless
011 Plastic Plate 1 Provide drill information
012 Large Case R 1 Hold in parts
013 Large Case L 1 Hold in parts
014 Clutch Trigger 1 Move clutch
015 Screw 3 Hold motor to chuck
016 Motor 1 provide torque

Function/Purpose:

Spin "bits" with a specified torque (variable stepping torque)

  • many different types of "bits"
  • Drive screws
  • Drill holes
  • removing stripped bits
  • Mixing paint/batter/dough
  • pumping water w/ drill powered pump
  • impromptu dremeling
  • binding things
  • home construction
  • alignment
  • safety

Inputs/Outputs:

  • INPUTS: Axial force
  • INPUTS: Trigger Pull
  • INPUTS: Electricity (battery)
  • INPUTS: Countertorque (resist what motor implements)
  • OUTPUTS: Rotational motion
  • OUTPUTS: torque

Use and Basic operation:

(scenario where putting screw in wall)

  1. Charge Battery
  2. Remove battery from charger
  3. Slide battery into drill
  4. Select bit/tool
  5. Loosen Chuck
  6. insert bit and tighten chuck
  7. select "cut-off" torque
  8. engage drive or gear
  9. Place head of screw on bit.
  10. Hold head of screw to bit (with hand).
  11. Place Tip of screw to desired object
  12. Partially squeeze trigger to provide low rotation-speed at first. All this while pushing axially.
  13. once screw's thread catch the wood, pull trigger to increase torque/omega.
  14. consistantly adjust to make sure bit is in line with screw.
  15. Let go of trigger when screw at desired location.

Different Users / Use Scenarios

  • weak wrist/grip
  • shaky hands
  • can't push hard enough
    • tightening Chuck
    • Actual drilling into material
  • Dead battery
  • Improper/Hard surface
  • Screw stripping
  • Screw alignment
  • Wrong bits.
  • Aligning bit correctly within chuck
  • Poor eyesight
  • Poor hand-eye cooridnation
  • Over-torquing (too soft a surface)
  • Poor lighting
  • no hands
  • tight areas/corners (awkward shape)
  • Hard time hearing maybe can't hear what's happening
    • screw stripping
    • overtorqueing
  • not strong enought to switch between F/N/R
